Switch between Tmux sessions using tmux a -t session_name․ List all active sessions with tmux ls․ Detach from a session with Ctrl+b d‚ allowing you to switch to another session․ Use tmux attach -t session_number to switch by session number․ This enables efficient multitasking and seamless navigation between different workflows‚ enhancing productivity for users managing multiple terminal sessions simultaneously․
Working with Windows and Panes
Tmux allows easy management of windows and panes․ Create new windows with Ctrl+b c․ Split panes vertically with Ctrl+b % and horizontally with Ctrl+b "․ Navigate panes using Ctrl+b arrows․ Close panes with Ctrl+b x after pressing q to select․ Efficiently organize your workflow with these commands․
5․1 Splitting Panes Horizontally and Vertically
In Tmux‚ split panes horizontally with Ctrl+b " and vertically with Ctrl+b %․ Use Ctrl+b arrows to navigate between panes․ To close a pane‚ press Ctrl+b x after selecting it with q․ This feature enhances multitasking by allowing multiple terminal sessions within a single window‚ boosting productivity for developers and system administrators․ Customize your workflow with efficient pane management․
5․2 Navigating Between Panes and Windows
Navigate panes using Ctrl+b arrows and switch windows with Ctrl+b n or Ctrl+b p․ Use Ctrl+b w to view a list of windows․ Press Ctrl+b q to display pane numbers for quick selection․ These shortcuts enable seamless multitasking‚ allowing users to efficiently manage multiple sessions and focus on specific tasks without losing productivity․
Copy Mode and History
Enter copy mode with Ctrl+b [ to scroll and copy text․ Use Ctrl+c to copy and Ctrl+v to paste․ Navigate history with Ctrl+b PgUp and Ctrl+b PgDn․
6․1 Entering Copy Mode
To enter copy mode in Tmux‚ press Ctrl+b [․ This allows you to scroll through the buffer and select text․ Use arrow keys or Ctrl+j/Ctrl+k to navigate․ Press Space to start selecting and Enter to copy․ Use Ctrl+v to paste the selected text elsewhere in the session․ This feature is essential for efficient text manipulation within Tmux․
6․2 Copying and Pasting Text
In Tmux‚ after entering copy mode with Ctrl+b [‚ select text by pressing Space and moving with arrow keys․ Press Enter to copy the selected text to the buffer․ To paste‚ use Ctrl+b ]․ The copied text remains in the buffer until overwritten‚ allowing easy reuse across sessions and panes․ This feature streamlines text manipulation and enhances workflow efficiency in Tmux․
